They are generally thought to be called wisdom teeth because they appear so late â much later than the other teeth, at an age where people are presumably wiser than as a child, when the other teeth erupt. The term probably came as a translation of the Latin dens sapientiae.
A wisdom tooth or third molar is one of the three molars per quadrant of the human dentition. It is the most posterior of the three. Wisdom teeth generally erupt between the ages of 17 and 25. Most adults have four wisdom teeth, one in each of the four quadrants, but it is possible to have fewer or more, in which case the extras are called supernumerary teeth. Wisdom teeth commonly affect other teeth as they develop, becoming impacted. They are often extracted when this occurs.
